RSS, Atom, Feh.
The syndication war is once again in fyll swing. Google has switched its users from RSS to Atom. Winer explains this as the first step toward introducing a new Google client; by moving lots of users away from RSS, Google ensures plenty of feeds will work with their new software but not with Radio Userland and other software that's already deployed. News.com covers the story in what Winer describes as a food fight.
Bad for users, and very bad for developers. (Have you noticed how little new syndication software is showing up lately?)
